That comic is fun and all, but the specific examples are things people actually do to reduce traffic speed. Painting lines that turn a two way road into a single lane for a single car length is common for low speed roads in order to force cars to take turn passing it, thus reducing speed. Cutout of pedestrians is extremely common, especially in the country area where they want to remind drivers to slow down next to homes. Sometimes they wear vests to look a bit like traffic police, through that practice is a bit (more?) illegal. If I remember right, when that comic came out there was a HN thread discussing exactly those things. Those tricks are not done in order to murder people, but they might confuse a computer.
